Preheat your oven to 400°F and line a baking sheet with parchment paper.
Dice the yellow potato into small, uniform cubes and toss with 1 teaspoon of olive oil and a pinch of sea salt.
Spread the potatoes on the baking sheet and roast for 25 minutes, or until golden and crispy on the edges.
While potatoes roast, prepare or reheat the beef bolognese by simmering the ground beef, tomato puree, minced garlic, oregano, salt, and pepper in a skillet over medium-low heat.
In a small bowl, whisk together the remaining 1 teaspoon of olive oil and the balsamic vinegar to create a simple dressing.
Place the mixed greens in a salad bowl and toss with the balsamic dressing until the leaves are evenly coated.
Spoon the warm beef bolognese sauce over the roasted potato cubes in a shallow bowl.
Serve the fresh garden salad on the side for a complete, nutrient-dense meal.
